Select path and filename - getpf.m

It enables to put path and filename into variables

The function is intended for putting names of directory and file into variables which may be used later for reading or writing files. It is beneficial in cases when searching files for processing by browsing a directory tree.

The function starts in a required point of a tree and displays contents of the subdirectory. A user may select an item from the list by one of two ways:
- entering one of displayed names, or
- paste and copy a name to prompt.
Yet another way to reach the required name exists - answer by pushing any key to the prompt until the name you need is displayed. Then, accept it by pushing ENTER. As soon as a file name is accepted the function returns path and name of the selected file.

The function needs another function from FEX, inp.m, #9033
