Ballistics calculator app

Just started work on this earlier, gonna take a while for sure, but I think it will be a cool useful app for re-loaders and precision shooters, plenty of online calculators but not much in the way of local apps for Linux. Very very basic to start with, I start simple and then do one tiny feature at a time, got a basic cli math engine working based on just a flat trajectory (muzzle perfectly level and parallel to the ground).

Example: .308 168gr BC=0.450 MV=2700 fps

Range(yd) | Drop(in) | Velocity(fps) | Time(sec)

0           | 0.0        | 2700          | 0.000
50         | -0.6       | 2606          | 0.057
100       | -2.5       | 2511          | 0.116
150       | -5.8       | 2416          | 0.177
200       | -10.6     | 2320          | 0.240
250       | -17.0     | 2224          | 0.306
300       | -25.1     | 2127          | 0.375
350       | -35.2     | 2028          | 0.447
400       | -47.4     | 1927          | 0.523
450       | -61.9     | 1824          | 0.603
500       | -79.0     | 1717          | 0.687
550       | -99.2     | 1605          | 0.778
600       | -122.6   | 1488          | 0.875
