  <#
.SYNOPSIS
    Takes [hashtable] input and writes the code that would create a hashtable with that information.
.DESCRIPTION
    Takes [hashtable] input and writes the code that would create a hashtable with that information.
.PARAMETER Hash
    The hash to be defined
.PARAMETER VariableName
    The name of the hash table variable
.PARAMETER Ordered
    Switch to use [ordered] when created hash, will sort entries by value
.PARAMETER QuoteField
    Switch to enclose the name and value attributes in single quotes
.EXAMPLE
    @{ A =1; B=2; C=3} | Write-StringHash

    $StringHash = @{
        C = 3
        B = 2
        A = 1
    }
.EXAMPLE
    @{ A =1; B=2; C=3} | Write-StringHash -QuoteField

    $StringHash = @{
        'C' = '3'
        'B' = '2'
        'A' = '1'
    }
.EXAMPLE
    @{ A =1; B=2; C=3} | Write-StringHash -Ordered

    $StringHash = ([ordered] @{
        A = 1
        B = 2
        C = 3
    })
.EXAMPLE
    @{A =1; C=3; B=2} | Write-StringHash -Ordered -VariableName MyHashTable

    $MyHashTable = ([ordered] @{
        A = 1
        B = 2
        C = 3
    })
