Lipid information

[ReneRanzinger]

• For now we should require PubChem IDs for lipids
• There should be a retrieve option from PubChem for the sequence similar to Glycans

Undone parts moved to #25

[ReneRanzinger]

• There are dummy examples they should be placeholders
• Use valid input as place holder (PubChem ID, Smiles)
• The fields can not be empty, at list one needs to be provided

[ReneRanzinger]

Open issues:

• Use valid input as place holder (PubChem ID, Smiles)

New issues:

• Its suffient to provide one (PubChemId OR lipid sequence)
• Can we validate the PubChem ID using one of their APIs?
• Rename "Lipid Sequence" to "Lipid Sequence (Smiles or InChI)"

[ReneRanzinger]

Lipid sequence disappeared. Was that moved into a production ticket?
