/* According to emscripten's design, we need our emscripted library to be executed
with a 'window' object as its global scope.
Note: that holds on emscripten's functions too, that is they need to be *explicitly*
run with some 'window' object as their global scope. In practice, given a function
'foo' pointing to some emscripted function, that is accomplished by the mean of 'call()'
or 'apply()' methods; so, being 'someWin' a 'window' object, the statements
foo.call('someWin', arg1, .., argN) or foo.apply('someWin', ['arg1', .., 'argN']) will
execute foo(arg1, .., argN) with 'someWin' as its global scope.
See http://www.bennadel.com/blog/2265-changing-the-execution-context-of-javascript

'GNUNET_free' in the wrapper)
- 'GSfunctionName' and 'GSALLfunctionName' comply to the same convention respect to
GNUNET_STRINGS_* realm.
- 'TWRfunctionName' takes its code from 'TALER_function_name' in the wrapper.
- 'TWRALLfunctionName' takes its code from 'TALER_ALL_function_name' in the wrapper
and returns a pointer that must be deallocated using 'TWRgnunetFree' (or a function
provided by some emscripted routine) (the 'wrapper' is an additional layer written in
C that does some struct(s) manipulations where that is uncovenient to do from JavaScript.
Currently located at '../../emscripten/testcases/wrap.c')
- The same applies to 'TfunctionName' and 'TALLfunctionName', to indicate that the
