Extract a variable from argument information across calls

This function extracts one piece of information from each of the calls collected via collectArgInfo via trace.

gatherArgInfo(x, var, paramNames = names(x[[1]]))

`x`	the list obtained from each call to the function being traced and each element is a list corresponding to each parameter/formal argument in that function
`var`	the name of the variable to extract from the list of call information. For the detault information function `getParamInfo`, this should be one of `class`, `type`, `length`, `nrow` and `ncol`.
`paramNames`	the names of the parameters which is typically taken from the call information but can be provided by the caller if appropriate.

A data frame with as many columns as there are parameters/formal arguments in the function that was traced.
