Alternate grade stored as structured registered grades

[scd]

Currently alternate grades can be parsed (eg 8- [6a+ A1]) but the system extracts only the best grade as it's registered grade (ie 8-). However there is a second grade 6a+ A1 which is not be stored as a structured grade for the route.

Enhance data structure to create multiple alternate registered grades. There may be 0, 1, 2 or more alternate grades. There needs to a concept of a primary and display order.

Discuss implications and business rules for:

• Displaying on route cards
• Facet search
• CPR
• Selecting the grade for ascents
