MACROFILTER
filter
MACROFILTER converts a macro into a filter which can be used with the FILTER framework
For each equivalence classes in the filter set of Geo Time Series™, the macro will be called with the following elements on the stack:
[gts], {labels_equivalence_class}
After each call the macro is expected to leave a list on the stack.

Examples
// Parameter list for FILTER
[
// Create a new GTS list
[
// Create a GTS with label name='foo'
NEWGTS 'gts1' RENAME { 'name' 'foo' } RELABEL NOW NaN NaN NaN 42 ADDVALUE
// Create an other GTS with label name='bar'
NEWGTS 'gts2' RENAME { 'name' 'bar' } RELABEL NOW NaN NaN NaN 42 ADDVALUE
// Create an other GTS with label 'foo'
NEWGTS 'gts3' RENAME { 'name' 'foo' } RELABEL NOW NaN NaN NaN 42 ADDVALUE
]
// List of labels to compute the equivalence class
[ 'name' ]
// Definition of the macro to apply
<%
// Store the Set of GTS on a variable
'gtsList' STORE
// Store the Set of Labels that forms the equivalence class on a variable
'labels' STORE
// Just push back the list on the stack
$gtsList

// The appliance of this filter generate a list that contains 2 lists
// First one contains the series that match 'name' == bar, second one 'name' == foo
