Nonexistent function "getNumber" called in Attr2MapOptions#toOptionValue()

[fivegreenapples]

I noticed some possibly unintended code...

Line 74 of attr2-map-options.js (line correct at commit:8a7e8db ) contains a call to getNumber().
This function doesn't exist in the code base so this always triggers an error - which is then caught and the value is handled further on in the toOptionValue() method. So this seems an odd bit of code, but perhaps it's a work in progress.

Relevant snippet given below:

try { // 1. Number?
    output = getNumber(input);
} catch(err) {

@fivegreenapples thanks for reporting this. It might have never implemented properly, I think.

I should remove out this code.
