Changes from kdb-tick

BREAKING Changes that affect processes outside of tick:

• time column is now expected to be timestamp, not timespan

SEMI-BREAKING Changes that affect processes inside of tick:

• .u.w renamed to .u.subs
• renamed .u.m to .u.h, h for handle

NON-BREAKING Changes that are purely internal:

• comments... comments everywhere!
• whilst time and sym column are required, they do not need to be the first two columns of a table
