.SYNOPSIS
    Function is getting Task Categories informations from GLPI
.DESCRIPTION
    Function is based on TaskCategoryId which you can find in GLPI website
    Returns object with property's of Task Categories
.PARAMETER All
    This parameter will return all Task Categories from GLPI
.PARAMETER TaskCategoryId

    PS C:\> Get-GlpiToolsDropdownsTaskCategories -All
    Example will return all Task Categories from Glpi
.EXAMPLE
    PS C:\> 326 | Get-GlpiToolsDropdownsTaskCategories
    Function gets TaskCategoryId from GLPI from Pipline, and return Task Categories object
.EXAMPLE
    PS C:\> 326, 321 | Get-GlpiToolsDropdownsTaskCategories
    Function gets TaskCategoryId from GLPI from Pipline (u can pass many ID's like that), and return Task Categories object
.EXAMPLE
    PS C:\> Get-GlpiToolsDropdownsTaskCategories -TaskCategoryId 326
    Function gets TaskCategoryId from GLPI which is provided through -TaskCategoryId after Function type, and return Task Categories object
.EXAMPLE
    PS C:\> Get-GlpiToolsDropdownsTaskCategories -TaskCategoryId 326, 321
    Function gets Task Categories Id from GLPI which is provided through -TaskCategoryId keyword after Function type (u can provide many ID's like that), and return Task Categories object
.EXAMPLE
    PS C:\> Get-GlpiToolsDropdownsTaskCategories -TaskCategoryName Fusion
    Example will return glpi Task Categories, but what is the most important, Task Categories will be shown exactly as you see in glpi dropdown Task Categories.
