TODO list for CD->SBGN

[royludo]

• logic gates

• modifiers pointing to direct links (without process) -> abandoned, not valid SBGN

• anchor points for receptors

• and truncated proteins

• reversible reactions

• keep style information

• keep notes

• residues for NA features

• style consistency for process/logic gates

• clone markers

• entities pointing to UNKNOWN logic gates must point directly to concerned process

• MIRIAM annotations

• label location for complexes

• logic gate reactions
