.SYNOPSIS
Writes verbose information about the invocation being entered.

Used to trace verbose information when entering a function/script. Writes an entering message followed by a short description of the invocation. Additionally each bound parameter and unbound argument is also traced.
.PARAMETER Parameter
Wildcard pattern to control which bound parameters are traced.
