The bread and butter of this script is the function Get-PropertyFrequencies
This function takes two mandatory arguments ([string]$Property, [PSObject]$Object) - given [string]$Property is an existing property in [PSObject]$Object
Get all unique values of a property found in the object
Initialize a new object with a property of the specified property and a property of Count
For each unique value in all the unique values found for the property in the object,
- If unique value is found to be of type
[DateTime], then take note for later - Copy unique value to new object and set count to 0
If unique value of property found to be of type [DateTime], then change the format to "yyyy-MM". This is done to actually receive useful information for analysis instead of compare included minutes.
For each value in the object:
- Search through all unique values found in the object
- If the value of the current object is equal to the current unique value, then add to Count
Return the new object that contains unique values, a count, and occurring frequency of those values found in the original object
