Quantlet:		summarize
Description:		provides a short summary table (min, max, mean, median standard error) for all columns of a data matrix. An additional vector of name strings can be given to identify columns by names.

Usage:	`summ=summarize(x{,xvars})`
Input:
	`x`	n x p matrix, the columns correspond to the variables.
	`xvars`	optional, p x 1 string vector, variable names. Note, that only up to 15 characters are used.
Output:
	`summ`	string output, containing summary table.
