[Health-dev] frl search issue

[tumashu]

After pip install requests, frl can be showed,

when we use virtualenv to install gnuhealth-client,  gnuhealth plugins's installation

will need more step:-)

for frl,  I have faced a bug:

Whan I click "search" buttom multi times, for search same string,

the results will show multi same result. for example:

A question is that:  frl is so importent, is it possible code it as

a gnuhealth module instead of gnuhealth plugin?
