本库主要提供一个漂亮而强大的自定义 SeekBar，进度变化由提示牌 (sign)展示,具有强大的属性设置，支持设置 section(节点)、mark(标记)、track(轨迹)、thumb（拖动块）、progress(进度)、sign（提示框）等功能

主要功能

• 强大的 track（轨迹）和 second track （选中轨迹）的最小值、最大值、轨迹粗细，颜色等设置；
• 灵活的数字显示，支持设置进度展示、节点文本展示采用整数还是浮点数；
• 支持设置进度单位，例如 10s,15km/h、平方，对数等；
• 支持手柄拖动块 thumb 半径、颜色、阴影、透明度等；
• 支持节点个数、文字大小、颜色设置；
• 支持指示牌宽高、颜色、圆角半径、三角 arrow 指示、border 边框、跟随 thumb 移动等；
• 支持设置拖动进度监听回掉；
• 支持格式化进度数字，完全自定义进度样式
