-- To show a dialog, call this function. 
-- The first parameter should be the name of the dialog (as definied in either InGameDialogs or PreGameDialogs). 
-- The second parameter should be an array table, containing any data that will be needed in the callback functions in the dialog
--      you want to display. 
-- The third parameter is a table, which contains parameters used when filling out the strings in your dialog.
--
-- If the main text in the dialog has 2 parameters (e.g "Hello <<1>> <<2>>"), then the 3rd parameter should contain a subtable called
-- mainTextParams which itself contains 2 members, the first will go into the <<1>> and the second will go into the <<2>>. The 3rd parameter
-- in ZO_Dialogs_ShowDialog can also contain a titleParams subtable which is used to fill in the parameters in the title, if needed.
--
-- If the sub text in the dialog has 2 parameters (e.g "Hello <<1>> <<2>>"), then the 3rd parameter should contain a subtable called
-- subTextParams which itself contains 2 members, the first will go into the <<1>> and the second will go into the <<2>>.
--
-- So as an example, let's say you had defined a dialog in InGameDialogs called "TEST_DIALOG" with
--      title = { text = "Dialog <<1>>" } and mainText = { text = "Main <<1>> Text <<2>>" } and subText = { text = "Sub <<1>> Text <<2>>" }
-- And you called
--      ZO_Dialogs_ShowDialog("TEST_DIALOG", {5}, {titleParams={"Test1"}, mainTextParams={"Test2", "Test3"},  subTextParams={"Test4", "Test5"}})
-- The resulting dialog would have a title that read "Dialog Test1" and a main text field that read "Main Test2 Text Test3" and a sub text field that read "Sub Test4 Text Test5".
-- The 5 passed in the second parameter could be used by the callback functions to perform various tasks based on this value.

-- Dialogs themselves (see InGameDialogs.lua, etc.) must contain at least a "mainText" table, with at least the "text" member.
-- mainText.text is filled in using the mainTextParams subtable of the table passed in the 3rd parameter to ZO_Dialogs_ShowDialog.

-- The mainText table can also optionally contain:
-- An "align" member to set the alignment of the text (TEXT_ALIGN_LEFT, TEXT_ALIGN_RIGHT, or TEXT_ALIGN_CENTER....left is default).
-- A "timer" field, which indicates that a certain parameter should be treated as a sceonds in a timer, and converted to time format
--      (so if mainText contains "timer = 1", the 1st parameter in mainText.text is converted to time format before being placed
--      in the string).
--
-- subText should just not be shown if not set and will not be shown if no mainText exists
--
-- Dialogs can also optionally contain:
-- 
-- A "title" table, which works the same way as "mainText" ("text", "align" and "title" fields are allowed), no title is shown if "title" is not set.
-- A "noChoiceCallback" field, which is executed when the dialog is closed without making a choice first.
-- A "hideSound" field, which is a sound id to be played when the dialog is closed without selecting an option
-- An "updateFn" field, which should be a function. If present, this function is called on each update when this dialog is showing.
-- An "editBox" field, which adds an edit box to the dialog. It can specify:
--      textType = The type of input the edit box accepts.
--      To get the value in the editbox, use ZO_Dialogs_GetEditBoxText.
-- A "warning" table, which works the same way as "mainText", which shows some red text at the bottom of the dialog to call attention to the specific action that is occuring
-- Finally, the is a "buttons" table, in which each member corresponds to a button. Dialogs support a maximum of 2 buttons.
-- If the buttons table is present, each of it's members in turn MUST contain a "text" field. Also, each button can optionally contain:
--      A "callback" function field (whose first parameter should always be "dialog"....use "dialog.data[i]" to reference the ith data member passed in).
--      A "clickSound" field that defines what sound to play when the button is clicked.
-- An option to show an animated loading icon near the main text, called "showLoadingIcon"
--
-- See the "DESTROY_AUGMENT_PROMPT" and "DEATH_PROMPT" dialogs in InGameDialogs.lua for examples of dialogs that use these various fields.
