unlike an (existing) FAT, our maps could follow our own rules.

if we sort strings like this (alphabetic order over case)
Aa
aa
AB <=1
aB <=2
Ba
ba
BB
bB
instead of by ascii value
AB  <=1
Aa
BB
Ba
aB  <=2
aa
bB
ba
then, case insensitive bisection search works, as equal words are stored
close to each other.

i have implemented this as a specialized std::map with a custom less
implementation. will try to get this under u_parameter.h...
