Write a function named funload that takes as its single argument the name of a file containing other functions. The purpose of funload is to make all functions in the named file available in the current shell; that is, funload loads the functions from the named file. To locate the file, funload searches the colon-separated list of directories given by the environment variable FUNPATH. Assume the format of FUNPATH is the same as PATH and the search of FUNPATH is similar to the shell’s search of the PATH variable.
