8b7a2e86b8 Avoid recompiling option_parser every time cmake runs. 
Switch to `configure_file`, which won't touch the output file unless
the contents change.

4e83e048ba Store percentages as ratios. 
Human-readable outputs (md) and CLI inputs still use percentages.
In-memory and machine-readable outputs (csv, json) use ratios.

This is the convention that spreadsheet apps expect. Fixes #2.

ea53972af8 Add nvbench.all metatarget. 
This builds all NVBench tests and examples without building targets in
any parent projects.

ab8fc13aac Simplify enum_type_list usage. 
Using C++17 auto template parameters enables two improvements:

1. Enum type no longer needed in `enum_type_list`:

```
// Old:
nvbench::enum_type_list<my_enum, my_enum::value1, my_enum::value2, ...>
// New:
nvbench::enum_type_list<my_enum::value1, my_enum::value2, ...>
```

2. New `nvbench::enum_type` helper cuts down on verbosity when writing
benchmarks

```
// Old
template <typename T, my_enum_a MyEnumA, my_enum_b MyEnumB>
void my_bench(nvbench::state &state,
              nvbench::type_list<T,
                                 std::integral_constant<my_enum_a,
                                                        MyEnumA>,
                                 std::integral_constant<my_enum_b,
                                                        MyEnumB>>)
{ ... }

// New
template <typename T, my_enum_a MyEnumA, my_enum_b MyEnumB>
void my_bench(nvbench::state &state,
              nvbench::type_list<T,
                                 nvbench::enum_type<MyEnumA>,
                                 nvbench::enum_type<MyEnumB>>)
{ ... }
```

9f6404bac6 Pad range max for floating point types. 
This avoids an annoying case where the max value is dropped due to
rounding errors.

Adds a few other missing test cases for `nvbench::range`, too.

Fixes #3.

60c94d9ed6 Add enum_type_axis and examples/enums.cu. 
- `enum_type_axis` simplifies using integral_constants with type axes.
- `examples/enums.cu` demonstrates various ways of implementing parameter
  sweeps with enum types.

b6d6b238fc Add timeout to blocking_kernel. 
This adds a diagnostic when a KernelLauncher syncs but does not pass
`nvbench::exec_tag_sync`.

c133784763 Add the first example. 
- New NVBench_ENABLE_EXAMPLES CMake option.
- examples/axis.cu provides examples of parameter sweeps.
- Moves testing/sleep_kernel.cuh -> nvbench/test_kernels.cuh
  - Accessible to examples and provides some built-in kernels for users
    to experiement with.
  - Not included with `<nvbench/nvbench.cuh>`.
