Namespace draw_residue_relations

Function to parse residue relations description array and style_obj, generating points, width and color scales to each relation object.
Relations between any residues or drawn elements follows the below syntax:
{
"source":"random_residue_source", //index OR residue_name+index of residue in relationship or valid element name such as: "DomainI;Helix1"
"target":"random_residue_target", //index OR residue_name+index of residue in relationship or valid element name such as: "DomainI;Helix1"
"raw_weight":possibly_random_residue_weight //number indicating strength of each residue or element relationship
"type": "type" //optional type object for describing multiple types of relationships in plor
