Lipid tail interdigitation

[p-j-smith]

Is your feature request related to a problem? Please describe.
Lipid interdigitation is thought to play a role in nanodomain registration and other membrane processes.

Describe the solution you'd like
An analysis tool to calculate the interdigitation of each tail in a lipid bilayer.

Describe alternatives you've considered

• A more general tool that can also calculate interdigitation in non-bilayer membranes.

• An analysis to calculate the overlap parameter between leaflets, rather than the interdigitation of each tail

Additional context
See Smith et al. for details on how to calculate the interdigitation of each acyl tail.
