[OpenSCAD] Digging into search( )

Hi Rusun,

Very briefly, vector and string 'index' counting starts at 0, not 1.

list1= ["abc",1,"def",2,"ghi",3]
 search( "def", list1 ) 

...will return '[2]' because list1[2]=="def"; list1[0]=="abc"

search( "def", list2 ) 

...will now return '[1,2]' because list2[1]=="def" and list2[2]=="def";

In my simplified search, all matches are always returned.  It is now up to
the user to decide how many/few to filter off and by what

I think that yes, I'll eventually add list/vector support to match_value,
however it will be considerably more involved to implement than the simple
'atomic' data structures. 

Support search for an N-dimension vector match could be fun+useful:
  - add 'tol[erance]' parameter to allow for 'close enough' floating point
'distance' matches.

Picking my battles. :-)
