Program which uses recursive destent to parse function in file "data.txt" and some variables with errors. Then uses diffirentiation ot estimate erroror of given function and with a help of LaTex make nice looking report.
Example of file "data.txt"
"<(gRr)/(4*({\pi})^2*{z_0})>
[g 9.8 0]
[R 114.6 0.5]
[r 30.5 0.3]
[{z_0} 214 1]
[{\pi} 3.14 0 ]"
