        .DESCRIPTION
        A function to search for files.

        Searches are performed by passing the parameters to Get-Childitem which will then recursively search through your specified file path and then perform a sort to output
        the most recently amended files at the top of the list.

        Outputs inlcude the Name, DirectoryName and FullName

        If the extension is not provided it defaults to searching for PS1 files (PowerShell Scripts).

        Using the switch you can choose to search the start or end of the file or selecting wild, will perform a wildcard search using your searchterm.

        .PARAMETER Path
        Species the search path. The search will perform a recursive search on the specified folder path.

        .PARAMETER SearchTerm
        Specifies the search string. This will define the text that the search will use to locate your files. Wildcard chars are not allowed.

        .PARAMETER Extension
        Specifies the extension. ".*" is the default. You can tab complete through the suggested list of extensions."
