Calling Convention
Call

Args
arg is a table
Results
r is a string
Usage Example
local s = {[11]=16}
local t = { [0]='finale', alice='joker', [s]='88'}
local r = sl.keyvalstr(t)
print(r)
--> 'table keys:values = {'

Description
The helper function keyvalstr returns a human readable string composed of the keys and values found in its sole argument. The keys and values are converted to strings before insertion into the resultant table. If the sole argument is not a table, then the string 'not a table' is returned. future versions of the library may alter the output slightly. the key* helpers aren't intended to convert data into a dostring compatible format; further additions to the library will address that need.
